In metrology laboratories, frequency meters are used to calibrate local oscillators of various electronic measurement equipment. In wireless communication testing, a frequency meter can be used not only to calibrate the master clock of a wireless communication base station, but also to analyze the frequency hopping signal and frequency modulation signal of a wireless station.

In traditional manufacturing enterprises, frequency meters are widely used in production testing of production lines. The frequency meter can quickly capture changes in the output frequency of the crystal oscillator. Users can quickly detect faulty crystal oscillator products by using the frequency meter, ensuring product quality.
